-Our inner surface is usually designed to be very smooth to reduce friction with the shaft and ensure smooth rotation of the shaft. At the same time, the part of the outer surface that fits with the bearing seat also has high precision to ensure good fit, so that the load can be evenly transmitted.

-To meet different lubrication needs, our surface may be designed with various forms of oil grooves and oil holes. The shape and distribution of oil grooves will be optimized according to specific application scenarios and lubrication methods. For example, spiral oil grooves can more effectively distribute lubricating oil evenly across the entire lining surface, while axial oil grooves are more suitable for situations that require rapid oil supply. The oil hole is used to introduce external lubricating oil into the interior of the liner, providing sufficient lubrication for the friction surface.

Metal Steel Bushing Split Bearing Bushes Material Characteristics

-The metal steel materials we choose for manufacturing have various excellent characteristics. Firstly, high strength is one of its important characteristics, which enables us to withstand large radial loads and partial axial loads. During mechanical operation, when the shaft is subjected to various forces, we can evenly distribute these loads onto the bearing seat, avoiding deformation, wear, and even fracture of the shaft due to excessive local forces, thereby ensuring the stability and reliability of the shaft system.

-Good wear resistance is also our key characteristic. During long-term use, the shaft will frequently come into contact with our inner surface and generate friction, and the wear resistance of metal steel can enable us to maintain good dimensional accuracy and surface quality in this friction environment. Even after long-term operation, our wear is relatively small, which extends the service life of the entire bearing system and reduces the frequency and cost of replacing components.

-Metal steel also has good thermal conductivity. During mechanical operation, the friction between the shaft and the bushing generates heat. If this heat is not dissipated in a timely manner, it may cause the temperature of the bushing and shaft to rise, thereby affecting their performance and fitting accuracy. And our metal steel material can quickly dissipate heat, maintain a lower working temperature, and ensure the normal operation of the equipment.

Function of Metal Steel Bushing Split Bearing Bushes

-Reducing friction and wear: This is one of our main functions. When the shaft rotates inside the bearing seat, we act as an intermediate medium, with a smooth inner surface in contact with the shaft, greatly reducing the friction coefficient between the two. Compared to directly contacting the shaft with the bearing seat, we can significantly reduce friction losses, make the rotation of the shaft smoother, and reduce energy consumption. At the same time, due to our own good wear resistance, we can withstand the friction of the shaft without being easily damaged, thus protecting the surface of the shaft and bearing seat and extending their service life.

-Supporting load: We can effectively withstand various loads transmitted from the shaft, including radial loads and partial axial loads. By evenly distributing the load onto the bearing seat, we can avoid deformation or damage to the shaft due to excessive local stress. In some high load mechanical equipment, such as large industrial motors, mining winches, etc., our supporting role is particularly important to ensure stable operation of the equipment under heavy load conditions.

-Absorption of vibration and impact: In many mechanical working environments, there will be varying degrees of vibration and impact, such as vibration generated by car engines during operation, and various impact loads on construction machinery during operation. We can utilize the elasticity and structural characteristics of metal steel materials to provide a certain buffering effect, absorb some vibration and impact energy, reduce their impact on the shaft and bearing seat, thereby protecting the components of the entire mechanical system, reducing the incidence of equipment failures, and improving the reliability and stability of the equipment.

-Positioning and guidance: We can provide accurate positioning for the shaft, ensuring that it maintains the correct position during rotation and preventing axial or radial displacement. At the same time, in some equipment that requires precise movement of the axis, such as the spindle system of a machine tool, we can also play a guiding role, making the movement of the axis more accurate and stable, thereby improving the machining accuracy and work efficiency of the equipment.

Lubrication method for Metal Steel Bushing Split Bearing Bushes

-Pre lubrication: Some types of products have already undergone pre lubrication treatment before leaving the factory. The manufacturer will add an appropriate amount of lubricant to the interior or surface of the liner, usually some grease or lubricating oil with good lubrication performance and wear resistance. In this way, after the installation of the equipment, there is no need to immediately lubricate it, and it can be put into use directly. The pre lubrication method is convenient and fast, providing good lubrication protection between the shaft and the bushing at the beginning of equipment start-up, reducing wear, and extending service life.

-Self lubrication: In addition to pre lubrication, we also have self-lubricating types. This is achieved by adding self-lubricating materials on the surface of the metal steel liner, such as polytetrafluoroethylene (PTFE) and molybdenum disulfide (MoS ₂). These self-lubricating materials have extremely low friction coefficients and good wear resistance, which can form a uniform lubricating film on the surface when the shaft and bushing move relative to each other, thus achieving automatic lubrication without the need for an external lubrication system. In addition, some self-lubricating bushings also use special pore structures to store lubricants. When the lubricant on the surface of the bushing is consumed due to friction, the lubricant in the pores will automatically seep out and replenish to the friction surface, maintaining a good lubrication state. The self-lubricating method greatly reduces the maintenance cost and workload of equipment, especially suitable for situations where regular lubrication maintenance is difficult, such as equipment working in harsh environments such as high temperature, high dust, or underwater.

-Forced lubrication: In some equipment with high lubrication requirements and harsh working conditions, we usually use forced lubrication. This method uses an external lubrication system, such as an oil pump, oil nozzle, etc., to deliver lubricating oil to the oil holes and grooves of the liner at a certain pressure and flow rate. Then, the lubricating oil forms a continuous oil film on the inner surface of the liner, separating the shaft from the liner and achieving good lubrication effect. Forced lubrication can ensure that there is always sufficient lubricating oil between the shaft and the bushing for lubrication and cooling under high load, high speed and other working conditions, effectively reducing friction and wear, and improving the reliability and service life of the equipment. But the forced lubrication system is relatively complex and requires regular maintenance and upkeep of lubrication equipment to ensure its normal operation.

Application areas of Metal Steel Bushing Split Bearing Bushes

-Automotive industry: In automotive engines, we are widely used for supporting and lubricating components such as crankshafts, camshafts, connecting rods, etc. For example, the crankshaft bearing liner needs to withstand the enormous pressure and impact force generated by engine combustion, while also ensuring the high-speed rotation accuracy of the crankshaft. Our high strength, wear resistance, and good lubrication performance can meet these requirements well, ensuring the stable operation of the engine. In addition, various types of our products are also used in the transmission, suspension system, and other parts of the car to reduce friction and wear between components, and improve the performance and comfort of the car.

-Machine tool industry: Machine tools are high-precision machining equipment that require extremely high precision and stability of the shaft system. We play a crucial role in the spindle, feed axis, and other components of machine tools. For example, the bearing liner of the machine tool spindle needs to ensure the rotation accuracy of the spindle at the micrometer level. Through high-precision machining and good lubrication performance, we can effectively reduce the vibration and thermal deformation of the spindle, improve the machining accuracy and surface quality of the machine tool. At the same time, in the transmission components such as guide rails and screws of machine tools, we can also reduce friction and improve transmission efficiency, ensuring the motion accuracy and stability of the machine tool.

-Mining and metallurgical machinery: These heavy machinery equipment typically need to withstand enormous loads in harsh working environments. For example, equipment such as crushers, ball mills, and hoists used in mining, as well as equipment such as blast furnaces, converters, and continuous casting machines used in the metallurgical industry, require high strength, high wear resistance, and good corrosion resistance for the bearing bushings of their key components. Our metal steel material can adapt well to these harsh working conditions, withstand huge impacts and friction, ensure long-term stable operation of equipment, reduce equipment maintenance and downtime, and improve production efficiency.

-Textile machinery and printing machinery: In these light industrial equipment, although the load is relatively small, high requirements are placed on the smoothness and accuracy of operation. We can reduce friction, lower noise, and improve transmission accuracy in components such as rollers and spindles in textile machinery, as well as in components such as rollers and transmission shafts in printing machinery. This ensures the quality of textiles and the accuracy of printed materials, and improves the efficiency and service life of equipment.
